Problems solved by technology

[0002] In industrial water level measurement, there are harsh environments such as high temperature, high pressure, negative pressure, vaporization, condensation, temperature and pressure changes, etc., but the measurement is required to be accurate, reliable, fast, and remote. The existing instruments have their own advantages and disadvantages, and in some respects they cannot fulfil requirements

Embodiment Construction

[0044] (1), open the upper and lower two holes from the steam drum wall, and connect the upper and lower connecting pipes of the mother water level measuring cylinder 19. Multiple sub buoys with different heights can be connected to the mother cylinder. The height of these two pipes will meet the height requirements of all sub-tubes drawn from the mother tube.

[0045] Master cylinders are not required. When there are multiple water level measuring switches with different heights, the mother barrel can reduce the openings on the wall of the steam drum, and the temperature in the mother buoy can be made closer to the temperature in the measured container, and can be installed close to the measured container, which can Reduce measurement errors.

[0046] (2), lead the heat tracing pipe from the steam side of the mother cylinder to trace the heat around the mother cylinder. It is also possible to install the mother barrel close to the wall of the steam drum, and do a good job ...

Abstract

The invention relates to a buoyancy-type liquid level meter for measuring the liquid level by applying a buoyancy, gravity and equilibrant balancing method, aiming at mainly solving the problem of influence of the temperature, pressure, vaporization and coagulation of a measured medium on measurement and overcoming the defects of an existing related measuring instrument. The method is not limited by the situation that the specific gravity of a floater is less than the specific gravity of measured liquid and can be used for measuring the liquid level by using a solid or hollow floater. The measuring meter suitable for multiple environments and multiple liquid levels can be manufactured according to specific conditions. The invention relates to a steam dome water level switch for measuring the steam dome water level inside an industrial boiler. The steam dome water level switch disclosed by the invention has high accuracy, high reliability and less drifting without frequent verification adjustment. Compared with a transducer, the steam dome water level switch disclosed by the invention has the advantages that intermediate conversion links are few, access of a computer system is not needed, an independent protective signal output is realized, complex electronic software and hardware are omitted, steam-water density compensation calculation is avoided, and the influence of steam-water density change and the influence of fast boiler load change are basically eliminated.

Description

technical field [0001] Industrial water level measurement field. Background technique [0002] In industrial water level measurement, there are harsh environments such as high temperature, high pressure, negative pressure, vaporization, condensation, temperature and pressure changes, etc., but the measurement is required to be accurate, reliable, fast, and remote. The existing instruments have their own advantages and disadvantages, and in some respects they cannot fulfil requirements. This design invention is to fill up the deficiencies in some aspects of the current related measuring instruments. Contents of the invention [0003] The present invention uses buoyancy, gravity, balance force three-force balance method to measure water level or other liquid levels. It is mainly to solve the influence of the temperature, pressure, vaporization and condensation of the measured medium on the measurement, and to fill in the shortcomings of the current related measuring instru...
